At least two ambulances and the Oklahoma Highway Patrol are at the scene.

Authorities said the helicopter was headed to the Creek Nation Community Hospital in Okemah to help with the transport of a patient. The helicopter took off from the Seminole Airport and had no patients on board.

The cause of the crash is still under investigation. However, Brown said that engine failure may be to blame and that the helicopter pilot found an open field to make the landing.
